Compare the specs for the new 3CX1500D7 vs the 3CX1200Z. It appears that it is
a very similar tube with bigger cooler and
filament designed to replace 3-500Z's. Downside is lower max frequency and
greater
drive requirements. It may suffer ffrom lower output at 30 MHZ like the
3CX1200A7.
In my opinion, the 3CX1500A7/8877 is a better tube for homebrew and new
applications.
Lower drive requirements from the exciter mean lower IMD, potential greater
efficiency at 30 MHZ, and much lower filament power requirements.
